Objective   To comprehensively evaluate the reporting quality of notifiable infectious diseases in Jiangxi province from 2017 to 2021, and explore evidence for the improvement of the reporting quality of infectious diseases.

  Methods   Stratified cluster multistage sampling was used to collect the data of notifiable infectious disease reporting in medical and health institutions in Jiangxi from 2017 to 2021. Software SPSS 22.0 was used for data statistical analysis, TOPSIS method was used to comprehensively evaluate the reporting quality of notifiable infectious diseases.

  Results   From 2017 to 2021, the reporting rate of notifiable infectious diseases in Jiangxi was 98.28%. The levels of medical institutions were divided into grade Ⅲ, grade Ⅱ, grade Ⅰ and non-graded from high to low. The reporting quality of notifiable infectious diseases in medical institutions decreased with the grade decrease. The top three prefectures with high quality of infectious disease reporting in Jiangxi from 2017 to 2021 were Yingtan, Jingdezhen and Pingxiang. The quality of notifiable infectious disease reporting of medical institutions with hospital information system (HIS) was higher than that of medical institutions without HIS, and the quality of notifiable infectious disease reporting of medical institutions with infectious disease reporting management system was higher than that of those without such system.

  Conclusion   The overall quality of notifiable infectious disease reporting of medical institutions in Jiangxi from 2017 to 2021 was high, but there were still problems such as underreporting, untimely reporting, incomplete and inaccurate reporting. The establishment of HIS system and the improvement of infectious disease reporting management of medical institutions can effectively improve the quality of infectious disease reporting.
